I think I already know the answer to this but I wanted to post for a second or more opinion. I replaced the cracked hinge with a new case and after putting it all together it won't turn on, mostly. The LED turns on dim green, then bright green, I can hear a click from the speaker and then it shuts off. I have tried reseating the cable for both the top and bottom screen and still nothing. Other than replacing the top screen or paying nintendo $75 to fix it does anyone have any suggestions?
